Dipolar axial compression permanent magnet motor

ABSTRACT

The present invention relates to a system and a method for improving the use of energy in an electric motor by inducing currents generated from magnets that result in an increase of primary power and creating, directing and introducing a counter current obtained from primary coils of the motor into a resonant LC circuit which is introduced as a transient secondary process to increase the overall efficiency of the motor. Furthermore, this motor produces rotational torque without using alternating magnet polarity, but rather magnetic compression that utilizes permanent magnets arranged in a dipolar manner around an axial plane.

BACKGROUND OF THE INVENTION

Numerous attempts have been made to increase the efficiency of electricmotors. Many of these attempts are set forth in patents and patentapplications such as:

U.S. Pat. No. 6,392,370, Bedini, Device and Method of a back EMFpermanent electromagnetic motor.

U.S. Pat. No. 7,230,358, Smith, DC Resonance Motor.

US Patent Application 2009/0045690, Kerlin, DC HomopolarMotor/Generator.

SUMMARY OF THE INVENTION

The present invention comprises a dipolar magnetic compression motorwhich includes primary coils that produce currents which are directedthrough an LC circuit in timed resonance for use in increasing theefficiency of the motor. This current is switched on and off through asecondary set of coils without the need to be stored. In anotherembodiment, an induced current from magnets which pass within closeproximity to the primary coils is directed to a power source andintroduced into a set of secondary coils. The motor creates rotationaltorque as a direct result of these magnets being repelled by bothprimary and secondary coils arranged in a dipolar axial manner.

Generally, motors of the present invention comprise a housing supportinga rotatable shaft and at least one nonferrous rotor disk mounted to theshaft for rotation therewith. At least two permanent spaced apartmagnets are mounted through the rotor with like poles aligned parallelto the shaft. A cylindrical support member is concentrically positionedaround the rotor to support ferrous-cored coils. At least two ferrouscored coils are spaced apart from each other and mounted to thecylindrical support member in juxtaposed relationship to the permanentmagnets on the rotor during rotation of the shaft. A timing wheel ispositioned on the shaft adjacent to the support member. Additionally, aHall effect device is fixed in a position so as to be influenced by thetiming wheel.

A control circuit is provided for controlling current to respectivecoils when activated by the Hall effect device. A circuit is alsoprovided for receiving current from at least one of the coils duringrotation of the rotor when at least one coil is not directing current tothat coil. The current received is directed to the control circuit forapplication to at least one of said other coils. By directing currentgenerated from the unactivated coils to the activated coils, substantialefficiencies are created which results in the less production of heat inthe motors of the present invention.

The dipolar magnetic compression comprises a pair of permanent magneticpoles of opposite polarity which are separated by a pre-determineddistance move within close proximity to a pair of intermittentlyactivated electromagnetic poles aligned in opposite polarity separatedby a pre-determined distance. These permanent magnetic dipoles andintermittently activated electromagnetic dipoles are aligned with thesame polarity, so their fields repel each other when electromagneticdipoles are activated.

As a magnetic dipole approaches an un-activated electromagnetic dipole,impedance drops in direct proportion to the square of the distancebetween the magnetic and the electromagnetic dipoles. Currents areinduced from the interaction between said magnetic dipole and saidun-activated electromagnetic dipole, of which are held withinelectromagnetic dipole for a time period determined by the time constantformed by a reactive LC circuit comprised of the electromagneticdipole's inductance and a fixed capacitance.

When impedance reaches a minimum value, un-activated electromagneticdipoles are activated at a time and for a duration pre-determined with acontrol circuit triggered by a Hall effect device. Once activated,primary currents combine with currents held within reactive LC circuit,thus repelling magnetic dipoles. Impedance rises in direct proportion tothe square of the distance between the magnetic and the electromagneticdipoles and return to an un-activated value as the magnetic dipoleexits.

In one embodiment of the invention, for example, current from theunactivated coils is used to increase the efficiency of the motor bydirecting and filtering it into a specifically calculated point ofresonance. In this embodiment, the circuits direct and switch thecurrent into and out of a secondary circuit. The capacitance in thiscircuit, when combined with the primary coils' inductance, is selectedfor a specific time constant to provide maximum current for theintroduction into the secondary circuit. The secondary circuit includesa) magnet position sensor and b) a pulse switching-driver stage. Inanother embodiment, digital pulse conditioning is accomplished by theaddition of c) pulse position control and d) pulse width control. Eachof these stages is optimized to achieve the desired resonance of a tunedLC circuit.

As a consequence of directing and introducing the generated current intoa secondary circuit, a lower amount of heat is generated in a motoremploying the present invention. Optimum performance is governed by theselection of component values that achieve a resonant state between thecapacitors and coils at a predetermined rpm having a desired torque.

The present invention achieves dipolar operation by positioning magnetsof the same polarity facing the respective stator (coils). Pulsedelectromagnetic fields are arranged to compress the magnets' north andsouth fields simultaneously, resulting in continuous rotation ratherthan the typical “push/pull” or alternating field arrangement ofconventional bipolar motors.

Accordingly, with the same or less input power, the present inventionutilizes dipolar axial compression together with thecounter-electromotive force current (herein referred to as “CEMF”) toprovide greater torque and efficiency. In a preferred embodiment of theinvention, a coil ‘core’ is made from laminated electrical steel toincrease the flux density of the magnetic field. Other ‘core’ types suchas grain oriented steels and ferro-composits are contemplated for use tofurther increase overall efficiency.

Various advantages of the motors of the present invention include:

-   -   A secondary circuit utilizes induced current spikes to provide        time to use the current generated rather than produce heat. For        example a 12 volt direct current input results in an induced        voltage of about 200 volts, which is reduced to 12 volts under        load.    -   These motors of the present invention can be made of non-metalic        component parts which can reduce weight and electrical shock        hazard. In one preferred embodiment of the invention, ultra high        molecular weight (UHMW) plastics are used for the stators and        rotor parts.    -   Increased energy efficiency achieved by introducing CEMF as a        secondary process.    -   Lower operating temperatures which extend bearing and coil life.

DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 and 2, a simplified embodiment of dipolar dc motorof the present invention is shown. A first stator plate 22 is affixed toone end of housing 23. Housing 23 is preferably made from a plastic suchas a PVC plastic. A second stator plate 24 is affixed to the oppositeend of housing 23, but facing first stator plate 22. A first bearing 25and a second bearing 26 are centrally positioned on first and secondstator plates 22 and 24, respectively, to provide support and a lowfriction surface for shaft 27. First and second bearings 25 and 26 arealigned to be flush with the respective inner edges of first and secondstator plates. In this embodiment, a rotor 31 is mounted on shaft 27 forrotation and spaced apart from first and second stator plates 22 and 24.Rotor 31 is made from a nonferrous material, preferably UHMW plastic.Rotor 31 includes eight nickel-plated Neodymium cylinder magnets 30 arepressed into eight equi-spaced openings near the outer the circumferenceof rotor 31. Magnets 30 are aligned with their magnetic polaritiesparallel to shaft 27. Rotor 31 is affixed to shaft 27 by a rotor fixingring (not shown).

In this embodiment, four coils 36 are used. Each coil is preferablyfabricated from a pre-determined length of hard-drawn copper enameled#22 wire and tightly and evenly distributed around a nylon bobbin 38utilizing an increased magnetic permeability from laminated iron cores39 consisting of three hundred 1.500″ long by 0.0015″ diameter strandsof welding wire. Laminated iron cores 39 are centrally and fixedlylocated within coils 36.

Coils 36 are mounted substantially equidistant around the circumferenceof first stator plate 22 and second stator plate 24 both stator platesfacing towards magnets 30 mounted through rotor 31 such that themagnetic poles are in direct alignment with magnetic poles coils 36.Electrical connections to first and second coils 36 are made by way ofcoil pins passing through openings in the first and second stator plates43.

A first semiconductor Hall device 41 a is mounted on the inner side ofthe stator and positioned to face rotor 31 to sense the position of eachmagnet as it passes within close proximity to Hall sensor 41 a duringrotation of rotor 31. Supply voltage and signal output of first Hallsensor 41 a are made by way of Hall cable 68 a (FIG. 2) passing throughfirst stator plate 22, then into first circuit board 49 and first socketconnector 51.

Additionally, referring to FIG. 2, a second equidistant arrangement offour coils 36 are mounted on second stator plate 26 facing magnets 30 onrotor 31. This second set is also in direct alignment along a parallelplane with first stator plate and facing the magnets with an oppositeset of magnetic poles. The second set of coils has electricalconnections made in an identical to those in the first set of coils. Asecond identical semiconductor Hall device 41 b is positioned to facerotor 31 for sensing the position of the magnets as they pass withinclose proximity to second Hall sensor 41 b during rotation of rotor 31.Second Hall device 41 b likewise mounted on the second stator plate witha supply voltage and signal output of second Hall sensor is supplied byway of a Hall device cable 68 b (see FIG. 2) identical to the first Hallcable.

In a presently preferred embodiment of the foregoing motor, a Darlingtoncontroller was used in the operation of the motor employing CEMF.

Referring to FIG. 1, the motor in this configuration reached a peakrotational speed of 3399 RPM and consumed 29.74 Watts of power. Bothprimary and secondary circuits were active in this test using CEMF whichwas obtained from the primary resonant transient filter circuit C1 andR1 (FIG. 3) and which is described in more detail below. In a comparisontest using the Darlington Controller with and without using CEMF, adifference of 5.23 Watts was observed. (see FIG. 14 a.) Also observedwas an increase of 459 RPM by utilizing CEMF.

A brief description of the Darlington circuit shown in connection withFIG. 3 as used with the embodiment shown in FIGS. 1, 2 and 2 a follows.In this Figure, primary coils 36 are shown individually as coils L1through L4 mounted on stator plate 22 within close proximity to rotormagnets 30. The north poles of rotor magnets 30 come within closeproximity to Hall device 41 a during rotation and triggers pre-drivertransistor 1. Pre-driver transistor 1 turns on and triggers drivertransistors Q1 through Q4, which actuate coils L1 through L4 to passcurrent simultaneously through each. Current flow through the coilscreates an electromagnetic field of the same polarity of magnets.Magnets 1, 3, 5 and 7 (FIG. 2 a) respond by repelling from coils L1through L4 in a direction determined by their wiring polarities.

The cycle repeats when the north pole of the second rotor magnet comesin close proximity to hall device 41 a, and continues as each successivenorth pole of the rotor's magnet comes in close proximity to hall device41 a.

During periods of time when Hall device 41 a is not influenced by thenorth pole of any rotor's magnet, the electromagnetic field around eachcoil L1 through L4 collapses and produces a combinedcounter-electromagnetic force (CEMF) that is directed by rectifiers D1through D4 into a transient filter composed of C1 and R1.

The combined inductance of coils L1 through L4, transient filter C1 andR1 create a LCR resonant circuit. Transient CEMF is directed into thesecondary driver circuit providing power for Hall device 41 b,pre-driver transistor 2, driver transistors Q5 through Q8 and coils L5through L8. In a complimentary and opposing manner, but not shown,secondary coils L5 through L8 are mounted within close proximity toevery other rotor magnet, but in opposition to primary coils L1 throughL4. The south poles of the rotor magnet comes within close proximity toHall device 41 b and triggers pre-driver transistor 2. Pre-drivertransistor 2 turns on, triggering driver transistors Q5 through Q8,which actuate coils L5 through L8, and pass current simultaneously.Current flow through the coils creates an electromagnetic field of thesame polarity as the magnets. FIG. 2 a. Magnets 1, 3, 5 and 7 respond byrepelling away from coils L5 through L8 in a direction determined bytheir wiring polarities. The cycle repeats when the south pole of thesecond rotor magnet comes into close proximity of hall device 41 b, andcontinues as each successive magnet's south pole comes within closeproximity to hall device 41 b.

During periods of time when Hall device 41 b is not influenced by anymagnet's south pole, the electromagnetic field around coils L5 throughL8 collapse and produce a combined counter-electromagnetic force (CEMF)that is directed by rectifiers D5 through D8 into a transient filtercomposed of C2 and R2. The resultant CEMF from the secondary stageremains within the circuit, but was not reintroduced in thisconfiguration.

Additionally, as each rotor magnet approaches each respective coil,currents are induced into each coil during driver ‘off times’ to provideincreased voltage over and above the supply voltage. When each magnethas moved away from the center of each coil, the coil driver transistorsbecome conductive at a time determined by the timing wheel to repel bothnorth and south poles of rotor magnets and creating dipolar magneticcompression.

In another preferred embodiment of the invention, a dual rotor dipolarmagnetic compression motor shown in exploded view FIG. 6. In thisembodiment, first and second rotors 98 and 107, respectively, aremounted on drive shaft 94 slightly apart from each other. Drive shaft 94is mounted to end plates 81 and 88 by means of bearing mounts 128 and130 secured to the respect end plate. As shown in FIG. 6, fourequi-spaced, axially aligned nickel-plated Neodymium cylinder magnets 96are positioned on each of the respective rotors substantially parallelto shaft 94. Shaft spacer 103 is positioned on shaft between firstbearing and first rotor 98. The magnetic polarities of the first andsecond rotor magnets 96 are positioned to face same magnetic polesopposite from each other. Timing wheel 105 is positioned on shaft 94between second rotor 107 and second bearing 130 and secured to shaft byway of two stainless steel set screws 109 placed one hundredeighty-degrees apart to rotate with the shaft 94.

A first coil 113 was fabricated from a length of, e.g., #23 hard-drawncopper enameled wire tightly wound around a “U”-shaped laminatedelectrical steel core consisting of approximately thirty layers of0.016″ thick, C4 coated enameled sheets. (See, FIG. 10). First coil 113is mounted through slots 115 in first inner housing, parallel to shaftand first rotor magnets 96. Likewise, two second “U”-shaped coils 117,identical to the first “U”-shaped coil, except wound with apre-determined length of, e.g., #20 hard-drawn copper enameled wire, areboth mounted through slots 115 cut into second inner housing one hundredeighty-degrees apart and wired as a series circuit.

Both first and second inner housings are fixed together by center fixingring 119. Notches 121 cut into opposing sides of center fixing ringaccommodate and hold one side of first “U”-shaped coil core and one sideeach of both second coil cores in position. Center fixing ring 119 isheld into place by stainless steel screws through outer fixing ringholes 123 and into first inner housing 84.

First support plate is pressed into outer side of first inner housingand fixed into place with four stainless steel machine screws throughsupport plate fixing holes 129, each located ninety-degrees apart andinto four threaded holes around the outer circumference of first innerhousing 84. First bearing, of which supports one end of shaft, first andsecond rotors spacer and the timing wheel is fixed into centered hole offirst support plate 128. Likewise, a second bearing is fixed into secondsupport plate 130. Second support plate 88 is pressed into outer side ofsecond inner housing and fixed into place on second support platesupport plate fixing holes 148, each located about ninety-degrees apartand into four threaded holes around the outer circumference of secondinner housing 159. First outer housing 132 is fixed into position bymachine screws through holes 133, into threaded fixing holes 122.Likewise, second outer housing 90 is secured in position by stainlesssteel machine screws through holes 137 and into four threaded fixingholes 124. The “U”-shaped coils are securely fixed into position by wayof six core mounting brackets 149 held in place with twelve steelmachine screws through core mounting bracket mounting holes 151 and intotwelve threaded u-core fixing hole, of which six through center fixingring 153, two through first outer housing 155 and four through secondouter housing 157.

Printed circuit board controller 141 is fixed into position on the outerside of second support place by way of brass screws 87 through boardmounting holes 145 and into board fixing holes 139 and positioning Halldevice 143 to sense location of a position magnet 188 in timing wheeland wires 161 from coils to be attached. Second outer housing 135 isfixed into place over second inner housing by stainless steel machinescrews through second outer housing fixing holes 136 drilled 90 degreesapart and into threaded second inner housing fixing holes 137.Additionally, first outer housing is fixed into place over first innerhousing by machine screws through first outer housing fixing holes 133positioned ninety-degrees apart and into threaded first inner housingfixing holes 135. End cap 139 is pressed into outer side of second outerhousing and secured with stainless steel machine screws through end capmounting holes 141 drilled ninety-degrees apart and into threaded secondouter housing end cap mounting holes 146. Input power to printed circuitboard is made through power connector 165 and power wires 147.

Circuit Description

Referring to FIGS. 4, 5, 6, 7, 8, 9 and 10, low voltage regulation isaccomplished by connecting input power from a DC power source toregulator circuit 159 to provide 5 volts of regulated power to: Halldevice 143, primary pulse conditioner 160, secondary pulse conditioner161, frequency to voltage converter 162, primary control logic 163 andsecondary control logic 164 circuits. Primary coils 117 are fixed in aparallel position with respect to second rotor magnets 107, 96, wherebyeach magnet's north pole and south pole are simultaneously positionedwithin close proximity to each primary coil core leg's north 170 andsouth 171 pole, respectively (FIG. 15). Likewise, secondary coil 113 isfixed into a parallel position to first rotor magnets 98, 96 with eachmagnet's north and south poles simultaneously positioned within closeproximity to secondary coil core leg's north and south poles,respectively.

When input power is applied to regulator 159, control and primary FETdrive circuits via circuit board 141 and position actuator magnet 158 intiming wheel 105, Hall device 143 is triggered to output a square wavesignal as an input to: primary pulse conditioner 160, secondary pulseconditioner 161, frequency to voltage converter 162, and primary controllogic circuits 163. The primary control logic circuit outputs a squarewave of a fixed pulse width to primary FET drive circuit 165 to drivecurrent through the primary coils. Current flow through the primarycoils creates electromagnetic fields which are aligned to be the samepolarity as the primary rotor magnets. As a result, primary rotormagnets respond by repelling away from electromagnetic fields generatedby the coils' core legs, thus rotating the rotor.

The resulting CEMF from primary coils are directed as input to secondarycontrol logic circuit and outputted to secondary FET circuit 166,driving current through secondary coil, creating an electromagneticfield which is aligned in such a manner as to be the same polarity asthe second rotor magnets. As a result of this action, second rotormagnet one responds by repelling away from electromagnetic field createby secondary coil core, thus contributing to an increase in the torqueon shaft. First rotor magnets are fixed approximately twenty-fivedegrees offset from second rotor magnets, but rotor offset may vary inother examples to maintain peak performance.

In the dipolar magnetic compression motors, this cycle repeats whenposition actuator magnet two's pole comes in close proximity to Halldevice. Likewise, rotor rotation continues as each successive positionactuator magnet's pole comes within close proximity to Hall device. Whenshaft rotation reaches a rate pre-determined by frequency to voltageconverter circuit, a stable pulse width is inputted to primary controllogic for maintaining shaft torque while drawing minimal current fromthe source, and continues to do so until input power is removed or shaftis loaded beyond available torque.

Referring to FIGS. 15 through 20 a third embodiment of the motor of thepresent invention is shown. In this embodiment a first mounting plate251 is affixed to one end of housing 253. A second mounting plate 252,identical to first mounting plate, is affixed to the opposing end ofhousing 253 in the same manner as first mounting plate, but facing theopposite direction. A first bearing 257 is mounted into the center offirst mounting plate to provide support and a low friction surface forshaft 259 to rotate through. First bearing is pressed into a centeredmounting hole 261 of first mounting plate for support and is securedinto position by a thin layer of cyanoacrylate adhesive. Similarly, asecond bearing 258, identical to the first, is fixed into centeredmounting hole of second mounting plate 252 in a manner identical to thefirst. First and second bearings are preferrably flush with the inneredges of both first and second mounting plates.

Referring to FIG. 16, five first nickel-plated Neodymium cylindermagnets 263, their magnetic polarities aligned parallel to shaft 259,are pressed into five equally spaced holes around the circumference ofrotor 267. Additionally, five second nickel-plated Neodymium discmagnets 269, their magnetic polarities aligned perpendicular to firstmagnets and shaft 259 are pressed into five second equally spacedopenings around the circumference of rotor 267. Shaft 259 passes throughcenter of rotor 267. Rotor 267 is centrally located on and secured toshaft by two identical fixing rings 273, with each fixing ring locatedon opposite sides of rotor. Each end of the shaft passes through firstand second bearings. Each one of five first laminated steel cores 289are affixed into each of five recessed slots 297 in first mountingplate. Likewise, each of five second laminated steel cores 296 aresecure in identical, but opposite handedness in second mounting plate251, in an identical manner as first laminated steel cores.

Both mounting plates and cores are oriented to face rotor. One each offive first coils with first and second cores are distributed and locatedin equidistant spaced mounting slots 297 in housing. Each first andsecond laminated steel cores are positioned in such a manner as tooverlap one another within the center of each first coil when assembled.Additionally, each one of five second coils 302 are pressed into 1.045″diameter holes equidistant and centered around the circumference ofhousing, perpendicular to and equally inter-spaced between each of fivefirst coils.

Within each center of said five second coils are fitted a thirdlaminated steel core 303, of which are fixed into position by an ampleamount of silicon adhesive to fill in the gap between core and hole.Circuit board FIG. 19 is secured on the outer side of second mountingplate. A first reed switch 305 is accurately positioned across slot 311to insure proper on-off timing of board. Likewise, second reed switch309 is accurately positioned across slot 305 to ensure proper on-offtiming of SCR2 and soldered onto said circuit board.

Description of Dipolar AC Motor Operation

Referring to FIGS. 15 through 20, dipolar motor operation begins byapplying an alternating current across the anode terminal of SCR1, SCR2,first and second reed switches and common terminals of coils L1-L10.South pole of a first rotor magnet (FIG. 15 b) is positioned withinclose proximity to first reed switch 305, of which becomes actuated bysaid first magnets south magnetic field. Output currents from first reedswitch pass through first current limiting resistor R2, firstpolarization diode D1 and into gate terminals of SCR1. Alternatingcurrents flow from the source, into the anode terminal of SCR1 and areoutput from its cathode terminal at a phase and of a duration determinedby first reed switch's on-off time.

Five first coils L1-L5 located in and around the circumference ofhousing 253 become energized as current flows from SCR1 cathodeterminal, through coil connecting wires 318, through first coils andthen return to the source, closing the circuit. Currents flowing throughfirst coils create an electromagnetic field of a north polarity andsouth polarity from both ends of first coils. North polarityelectromagnetic fields are coupled via north laminated cores 289 whichare in close proximity to north poles of first rotor magnets, of whichprovide an opposing force against said first magnets north poles, thusrepelling rotor along an x-axis. A first capacitor C1 connected inseries with first current limiting resistor R1 provides transientstorage. Said capacitor and said resistor values chosen to achieve spikeelimination for stabilization of SCR1. Simultaneously, south polarityelectromagnetic fields are coupled via south laminated cores 95 whichare in close proximity to south poles of first rotor magnets, of whichprovide an opposing force against said first magnets south poles, thusrepelling rotor along the same x-axis.

In another operation, south pole of a first rotor magnet 263 ispositioned within close proximity to second reed switch 309, of whichbecomes actuated by said first magnets south magnetic field at atwenty-six degree offset of said first magnet south position. Outputcurrents from said second reed switch pass through second currentlimiting resistor R4, second polarization diode D2 and into gateterminals of SCR2. Alternating currents flow from the source, into theanode terminal of SCR2 and are output from its cathode terminal at aphase and of a duration determined by second reed switch's on-off time.

Five second coils L6-L10 located in and around the circumference ofhousing 253 become energized as current flows from SCR2 cathodeterminal, through coil connecting wires 318, through second coils andthen return to the source, closing the circuit. Currents flowing throughsecond coils create an electromagnetic field of a north polarity andsouth polarity from both ends of second coils. North polarityelectromagnetic fields are not utilized in this example, but may be usedin other examples. Counter-electromotive force generated from secondcoils collapsing fields are suppressed by shunt diode D3. South polarityelectromagnetic fields are coupled via laminated cores 303 which are inclose proximity to south poles of second rotor magnets, of which providean opposing force against said second magnets south poles, thusrepelling rotor along a y-axis. A second capacitor C2 connected inseries with second current limiting resistor R3 provides transientstorage. Said capacitor and resistor values chosen to achieve spikeelimination for stabilization of SCR2. As each successive first magnetrotates into position to actuate first and second reed switches, thiscross-axis dipolar method of creating rotational torque continues untilsource power is disrupted or loading beyond available torque stallsrotor. In this example, an alternating current input of 60 Hz at 115Volts results in an unloaded shaft rotation of 720 RPM.
